To assist competing clubs with their planning, an independent draw was made for the semi-final line-up before details of the quarter final participants were known. This will see the winners of match 3 host the winners of match 2 whilst the winners of match 4 play the winners of match 1.
This translates into Leinster or Glasgow Rugby hosting Munster or Edinburgh Rugby whilst Dragons or the Scarlets can look forward to a home semi-final against Ospreys or Ulster.
The semi-finals will be played over the weekend of 6/7/8 May, kick-off times are to be confirmed. The Celtic Cup final will take place on Saturday 14 May at a neutral stadium in the home country of one of the finalists.
